一、产品简介:

淀粉酶包括α-淀粉酶(EC 3.2.1.1)和β-淀粉酶(EC 3.2.1.2)。淀粉酶催化淀粉水解生成还原糖,是生物体利用淀粉进行碳水化合物代谢的初级反应。生成的还原糖能使3,5-二硝基水杨酸生成棕红色得3-氨基-5-硝基水杨酸,在540 nm有吸收峰;通过测定540 nm吸光度增加速率,计算淀粉酶活性。

本试剂盒采用70℃加热钝化β-淀粉酶测出α-淀粉酶的活力,再与非钝化条件下测定的总活力(α+β)相比较,求出β-淀粉酶的活性。


二、所需仪器和用品:

可见分光光度计、1mL玻璃比色皿(光径1cm)、恒温水浴锅、台式离心机、可调式移液器、研钵和蒸馏水。

1、问:官网上试剂盒规格标注的“24样”、“48样”、“96样”是什么意思呢?

     答:“24样”、“48样”、“96样”是试剂盒规格,我们定义了试剂盒可以测多少样,对于试剂盒需要的试剂量都给足的。

          “24样”、“48样”、“96样”规格的试剂盒,可以检测24个样、48个样、96个样;即分别得到24个、48个、96个数据。


2、问:官网上试剂盒检测方法中"可见分光法/紫外分光法"与“微板法”是什么区别?

     答:分光法:指使用紫外可见分光光度计检测,若无紫外可见光分光度计,订购时务必咨询公司技术。公司分光法试剂盒采用的比色皿规格是:光径:1cm,容积:1mL, 狭缝宽3mm;

           微板法:指使用全波段连续酶标仪检测;若无全波段酶标仪,订购指标时务必咨询公司技术, 本公司微板法试剂盒内送96孔普通酶标板,客户无需另外购买耗材。


3、问:分光法试剂盒与微板法试剂盒是否能通用?

     答:公司针对用户实验室具备的实验仪器条件,做了两个体系的试剂盒。两种体系试剂盒检测指标的原理一样,结果可以通用,但是不同体系的试剂盒不可以相互混匀!
